This product has become much thinner than I expected, almost like water. Also the set says 5-7 minutes of work but it was a lot longer, more like an hour or more before it stopped working everywhere off the board. I mixed it very carefully in a 2:1 ratio using the measuring cups that came with it. I even tried 2 different batches, the second was closer to 1:1 with hardener, didn't help. I tried leaving it on the board and components for at least an hour and it didn't even start installing. If you want to support the elements on an exposed circuit board, this is not the material to use. In the end I cleaned everything up and went the other way with a different product. Even the next morning (24 hours later) the remaining mixed unused slime was still sticky and didn't settle. It can be suitable for filling the entire case or PCB cavity (total immersion). But I have no idea because I haven't used it. I have most of the $37 kit left over and I don't know what to do with it.
